How can I reuse or recycle expired sunscreen/sun lotion?

I do have a suggestion though, I had been cleaning up the bathroom and found old sunscreen lotion bottles, still full. I heard you can’t use them more than a year, because they go bad and won’t work any more. I have used them in the past longer than I was supposed to, but now they are definitely too old. Do you have any suggestions?

I didn’t know that about sun lotion but searching around the web, a lot of people do seem to advise adhering to the product’s expiry date. However, according to a dermatologist quoted on the Mayo Clinic website, it’ll probably be good for three years or until it hits its expiry date – whichever happens sooner. Apparently after that, it loses its effectiveness.

I’m not sure what should be done with it after that – it’s probably not moisturising enough to be used as a general body lotion. One argument would be to buy smaller quantities so you’re not wasting as much – but as they’re usually (always?) in plastic tubes or bottles, there would be a big knock-on plastic waste issue from doing that.

Hey! I did a post about this exact same problem on my blog a few months ago. I’ve always been told not to use the sunscreen leftovers from one summer to the other because it wasn’t quite as effective. So this year I use it during Winter time aswell, on the exposed areas like hands, face and neck. This way I’m still protected agauns the sun, because during winter the UV-B rays don’t automatically stop, you just don’t get sunburns because you’re not as exposed as during summer. And I think that good sunscreen is still pretty moisturising, so it works as a moisturiser as well :) if you’d like, check out my post about this issue : http://boladepensamento.blogspot.com/2011/01/protector-solar-no-inverno-sunscreen-in.html

I’ve stopped using chemical sunscreens as they can contain harmful ingredients and at any rate, my skin is so pale I actually had to throw them out well before the expiry. Anything over a year old and I would burn.

Not much you can do with expired sunscreen but in the future I would recommend buying a mineral-based sunscreen, which doesn’t deteriorate as fast.

The problem with all science is it’s still hypothesis. Wish we knew for sure the lifespan of sun screen Kenny’s wife religiously disposes of unused sunscreen after the summer months … a little bit over protective of the girls.

I’ve got a great use for expired sunscreen, in fact I wish I’d had two bottles today. Use it to restore old green plastic lawn furniture. I read about this on the web and gave it a try. It gave new life to some chairs I found in the alley and they almost look as good as new. I rubbed it into the faded white back, arms and aseat and left the chairs back in the sun. I then wiped off any excess. It is amazing, like an Armorall job without buying more stuff.

This would also work to restore old plastic pots that were once terracotta, brown or any dark colored plastic that has faded.

I disagree with “not moisturising enough to be used as a general body lotion.”
It is and a lot more.
Think of the all the damage the skin is exposed during summer: sun, chlorinated water, salty water, sand…A good sunscreen sends you home with your skin intact: not dry and patchy.
So I think a sunscreen makes for a great moisturizer. Maybe too thick for body lotion but perfect as hand lotion.
